Perhaps, possibly, or by chance; expressing uncertainty (Scottish and dialectal English).
From Scottish English, possibly from 'able' + the suffix '-ins' or related to Old Norse 'opt' (perhaps). The term survives in Scottish literature and dialect, meaning 'by some possibility' or 'perchance.'
Burns and other Scottish poets used 'ablins' constantly because it sounds musical—'ablins ye'll see me again'—yet English standardization made it sound archaic to non-Scottish ears. Dialects preserve these beautiful old words that formal English abandons!
